Title: Method for measuring texture change of alloy and method for estimating remaining service life of alloy
Inventor: SAITO MASAKAZU
IPC: G01N33/20
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To estimate the morphology of the second precipitated phase of an alloy by measuring the electric resistance of the alloy and, in addition, to measure the texture change of the alloy or estimate the remaining service life of the alloy. SOLUTION: When a stress is continuously applied to an alloy having such a texture that a matching second phase is precipitated in a mother phase 1 at a high temperature, a second precipitated phase grows in the direction perpendicular to stresses and such a texture that the phases 1 and 2 are arranged in a plate-like state perpendicularly to stresses in many cases. This texture is stable for a long time, but, when a tertiary creep stage starts, the texture changes to such a texture that the phase 1 is isolated in the phase 2 and the alloy is fractured. The phase 2 is a metallic compound in which atoms are regularly arranged and which has electrical conductivity higher than that of the phase 1. Therefore, when the arrangement of the two phases having different electrical conductivity changes, the electric resistance of the alloy also changes as a whole.  Therefore, the stage of a sample to be measured and the progress of a texture change in the sample can be measured and the remaining service life of the alloy can be estimated.
